MOSCOW, Idaho (AP) — State education officials are giving Idaho universities and colleges more time to submit their student enrollment numbers, which have been calculated on the 10th day of each new semester for more than two decades. The Lewiston Tribune reports the plan approved Thursday will allow the schools to delay the counting of fall semester students until mid-October, while spring enrollment won't have to be calculated until mid-March. Colleges and universities typically use the 10th day of class as a measuring stick because it cancels out students who enroll and then quickly drop off. The state Board of Education looked at giving institutions more time after some complained that by submitting their numbers on the 10th day, they were excluding a number of high school students earning college credits.
